Can Satellite Be The Answer to Your Business Broadband Needs?

By: John Shepler

You’re totally frustrated. Doing business today needs an Internet connection even if you only sell to local customers. You’ve checked out cable and DSL options. No way. Not where you are located. Hey, it’s not like you’ve left civilization. There must be SOME way to get high speed Internet… isn’t there?

In most cases, the answer is yes. You just have to forget about cables and fiber lines. If they aren’t already connected or very near by, it will cost a fortune to bring them in. Instead, look to the sky! Here’s a quick video that explains why:


Here are 10 key points to remember:

1. Satellite Internet for business can provide both primary and backup connectivity.

2. Available satellite broadband speeds have increased to surpass traditional T1 lines and DSL, even to rival fractional DS3 and cable carriers. Exede offers up to 15 Mbps download with 4 Mbps upload capability.

3. Since service is delivered via dish antenna, not even a traditional telephone line is needed, much less high speed telecom infrastructure. That makes it possible to have broadband connections to fishing camps, farms & ranches, rural agri-businesses, and any other enterprise that isn’t served by even 3G or 4G cellular. All you need is enough power to run the satellite receiver/modem, and that can come from power mains or a solar/battery & inverter off-grid system.

4. Primary 15/4 business Internet is available throughout the eastern half of the USA, plus the west coast and partial coverage in Arizona and Colorado. National coverage and higher speeds are coming with a new satellite in 2017. Lower speed 5/1 redundant services is available now in nearly all of the continental USA.

5. Installation can be completed in just 3-5 business days. No need to wait for massive construction projects.

6. Business data plans are available from 20 GB to 200 GB/month with the option to purchase additional data. For many smaller business operations, this is more than enough, although not suitable for frequently streaming HD movies and other video entertainment.

7. Latency is greater than you’d experience with land based fiber, wireless and optical services due to the 22,000 mile path up to the geosynchronous satellite. This may or may not be noticeable depending on how you use the Internet. VoIP telephone works over the satellite, but you need to allow a half second or so between speakers.

8. You’ll need a clear view of the southern sky about half way up from the horizon for the dish to “see” the bird.

9. Pricing is similar or even less than what you’d pay for a dedicated Internet line running 1.5 Mbps upload/download or many of the business cable broadband plans.

10. Don’t think that you are left out of the world of ecommerce or unable to interconnect your many branch offices or stores due to lack of telecom support. Satellite might be just the answer.

Gigabit Metro Fiber Ethernet Means Business

By: John Shepler

More and more companies are running out of bandwidth as demanding applications eat up every Mbps of LAN, MAN and WAN bandwidth they can access. Are you doomed to fight a losing battle or is there a good technical solution available?

More Bandwidth to the Rescue
Don’t expect to roll back the clock and be able to do business today and tomorrow with the connections you ordered yesterday. X.25 is long gone. T1 lines have about had their last hurrah. Ethernet over Copper is a temporary solution, at best, to buy you time for what you really need to do. That is, connect to the world via fiber optic bandwidth

But What About Cable?
Cable broadband, also called D3 or DOCSIS 3 for the technical standard, is actually a good solution for some applications. Just don’t kid yourself. That cable connection doesn’t really go very far until it hooks up with the cable company’s metro fiber plant. The junction box may be a few blocks away or it might be handing on the utility pole you can see from your office.

The same is true for T3 or DS3 bandwidth, the longstanding upgrade path from T1 lines. The connection to your equipment may be a pair of coaxial cables, but they only go out to the street. At they point they join up with a SONET fiber optic system owned and maintained by the local telephone company.

What’s Special About MetroE Fiber?
Ethernet is the newer and future-proof technology for carrying digital traffic on fiber optic systems. It is based on the same Ethernet standards used for your local area networks. Certain standards have been added to fit with carrier operations, but otherwise it is switched Ethernet.

That means the interface between your LAN and the carrier’s MAN or WAN is trivially simple. Just plug in and go, like you would with any router or switch. No special interface cards are needed. Chances are that the carrier who is providing your service will install a managed router at your business to define the network edge.

Metro vs Internet
Metro Ethernet, strictly speaking, is a network that serves a particular city or city plus suburbs. The most common use has been to interconnect business locations that are geographically close. These may include headquarters, data centers, warehouses and branch offices. Some companies choose to include suppliers and important customers on their MetroE network for high connection speed and security.

Metro Ethernet is a point to point or multipoint service that directly connects particular locations. You can elect to order ELAN service that actually extends your local network to the other locations. It’s just like you ran your own cables across town, but without the prohibitive expense of doing so.

The Internet is another animal. It’s actually a massive worldwide network made up of national, regional and city-wide networks that all agree to a common standard. Metro Ethernet is not the Internet, but it can connect to it. MetroE networks can also connect to each other over longer distances, especially when ordered through the same carrier.

Why Order Metro Ethernet?
You can think of Carrier Ethernet or Metro Ethernet as the new gold standard in telecommunications. It gives you high bandwidth connections that are easily scalable and low in latency, jitter and packet loss. You have exclusive use of the bandwidth you’ve ordered. It’s also generally covered by a service level agreement to ensure that you get the highest level of availability.

That’s important because the tradeoff between Metro Ethernet and Cable Broadband is not so much in the connection method. Cable provides you with a shared bandwidth service that varies in speed depending on how heavy the usage is. Service is generally on a “best effort” basis rather than any particular guarantees of performance or availability. Thus, the lower price for a given bandwidth level. Some businesses, especially smaller ones, find this tradeoff well worth making. Others with large user bases and critical applications may find that only dedicated service is acceptable.

By the way, many Cable companies also offer Metro Ethernet service on their fiber backbones. It’s a different class of service with a different pricing structure than the coax connected business broadband offering.

Is Metro Ethernet For You?
If you are running out of bandwidth or already at the limit, or simply want a service that can easily be upgraded in the future, you should take a serious look at Metro Ethernet for your business. You may be able to get a break on construction costs or even have them waived if you sign a long term contract, have high enough bandwidth requirements or can join forces with other business customers in your building. There are likely multiple carriers serving your area. Find out what each can offer with a set of competitive quotes for Metro Ethernet service now.

Long Range Ethernet Goes Beyond The LAN

Ethernet has grown from its inception in the 1980s to become the dominant Local Area Network (LAN) protocol. The big technical advance in this decade is the rise of Ethernet as a Metropolitan Area Network (MAN) and Wide Area Network (WAN) protocol of choice. It’s likely that when this process is complete it will be Ethernet as far as the eye can see. What is it that is driving this move to Ethernet everywhere and what advantages does it offer for your business?

What’s solidified Ethernet in the LAN for now and the foreseeable future is economy of scale. Nearly every piece of networking gear you can buy has standard copper or fiber Ethernet connectors. The most popular of these, of course, is the RJ-45 connector. You recognize it immediately without even having to look at the legends near the connector or any equipment manuals. Within the organization, everything plugs into Ethernet sockets to connect to the network.

The big disconnect occurs when you want your traffic to leave the confines of your building or campus. You might find a contractor who will interconnect businesses within an office or industrial park, but that’s about as far as you can install private network cable. You might get a little farther with optical line of sight or microwave wireless transmissions. However, if you want to be able to connect to the Internet or establish a private network around town or across the country, you need to use a telecom carrier.

The first carriers were local telephone companies. Today’s ILECs or Incumbent Local Exchange Carriers offer far more than telephone service. They have twisted pair copper bundles running to every home and business. They also generally have fiber optic cabling for their own use and to lease to major businesses. These services have their own unique protocols invented by the telephone industry to transport phone calls. Copper data transmissions use T-Carrier, such as T1 or T3. Fiber optic transmissions use SONET (Synchronous Optical NETwork) standards, such as OC-3, OC-12 and OC-48.

How do you connect an Ethernet protocol network to a T-Carrier or SONET protocol carrier? Very carefully! You need what’s called a protocol converter. This is generally in the form of a plug-in module for your router. The conversion process changes the signals and timing of one protocol to another so that they can exchange digital data.

This conversion process has worked well for decades, so why change it? The reasons are efficiency, new services and cost.

What’s happened is that new competitive carriers have emerged. These carriers don’t have the legacy of telephone company standards to support and have embraced IP networking for their regional and nationwide fiber optic networks. Since your network runs Ethernet and their network runs Ethernet, it seems logical to interconnect them via Ethernet.

The standardization of what’s called Carrier Ethernet by the industry standards group, Metro Ethernet Forum (MEF), has opened the door to handing off network traffic from business to carrier and between carriers within the Ethernet protocol. Getting rid of the conversions makes the process more efficient. More importantly, it has made possible services that you can’t get on the old telco networks. Notably, these are E-Line or Ethernet Line service and E-LAN or Ethernet LAN service. The difference is that E-Line connects two locations and E-LAN can connect multiple locations in a mesh network.

By keeping everything as Ethernet, it is now possible to bridge LANs at two or more locations at the layer 2 level using Ethernet switches. Essentially, you take all these individual LANs and join them to form one much larger corporate LAN.

Another advantage of using Carrier Ethernet to transport your traffic is that it was designed from the beginning to be easily scalable in much finer increments than the telco protocols. You install a port, say 100 Mbps, 1000 Mbps or 10 GigE, that sets the maximum bandwidth of your connection. However, you don’t need to order the highest speed that the circuit will support you can start off at a quarter or half of that and then increase your bandwidth when needed. Often, all that is needed is a call to your Ethernet service provider. The change can be implemented in hours or days because there are no equipment swaps that need to be made.

Finally, Carrier Ethernet has a significant cost advantage compared to bonded T1, T3 (DS3) bandwidth and SONET services. On a per-Mbps basis, Ethernet often costs just half of what you pay for the older technologies. That mean you can save money for the company on your next telecom contract or double your bandwidth for the same budget.

Does long range Ethernet meet your needs? A good way to find out is to get competitive quotes for both traditional bandwidth and Carrier Ethernetservices and compare cost and features.

Virtual Computing, Storage and Security for Latin America

Infrastructure as a Service (IaaS) and managed hosting have experienced rapid adoption by enterprise users in North America and Europe. Level 3 Communications is now offering a new set of data center services to enterprises in Latin America.

The countries of Latin America span North America (Mexico), Central America, the Caribbean and the continent of South America. This is an area of over 8 million square miles and 14% of the land surface of the globe that’s home to a population of almost 600 million. It’s also a region where major economic sectors include, banking, agriculture, manufacturing, commodities and tourism.

Level 3 Communications has a major commitment in Latin America, with operations in Argentina, Brazil, Chile, Columbia, Ecuador, Panama, Peru, Mexico, Venezuela, the United States (Florida) and the Caribbean region. They already have 15 world-class data centers located in the main business centers of Latin America. The connectivity is in place to support communications in-country, between countries and to the rest of the global community. Options include SDH Private Line, Wavelengths and Ethernet Wavelengths, Ethernet Transport, IP VPN, high speed Internet Protocol and more.

What’s exciting now is the opportunity for virtualized services in the cloud to replace local data center operations. Cloud computing, storage and security have the advantages of being quickly scaled, and paid for as an operating rather than capital expense.

Level 3 Dynamic Enterprise Computing offers virtual computing, storage and security elements with dynamic pricing based on resource consumption. Resource availability is assured, but not limited. You can rapidly scale, or burst, to cover unforeseen business activities. All the while, you are paying for what you actually use, rather than having to provision resources that may sit idle just to ensure that you have enough online to keep up with demand peaks.

Level 3 is a major force in cloud computing with the advantage of also being a major worldwide telecom carrier. You have a choice of public, private or hybrid cloud arrangements. You also have the connectivity you need. You can connect to the public cloud through Level 3’s core Internet backbone. For a private cloud, Level 3 offers MPLS, private line and wavelength connections.

One thing you might want to consider is converging your network to support both voice and data. This has the advantage of eliminating the redundant telephone network, but the options it opens up go far beyond simple wiring. Once you’ve substituted IP phones for the analog desk sets you have now, your voice communications will all take place over your local network and the WAN connections you have in place with branch offices and other remote business locations. This lets you bypass the telephone industry toll charges for interoffice calls.

The biggest change of all comes when you abandon the large and expensive in-house PBX telephone system in favor of a hosted PBX solution in the cloud. It works like a virtual server, only for voice communications. The service provider takes care of trunk lines to the public telephone system. All other calls stay on-net. You also have the option of integrating your smartphones and other mobile devices into a unified communications system. You’ll have the same services available in the field as you do in the office.

Do you do business in Latin America, North America or elsewhere in the world and need the high performance connectivity and data center services that help make an enterprise successful? If so, have a look at the suites of cloud computing and networking services available from Level 3 Communications and other top rate service providers.

Optical Ethernet Connections To The World

Fiber optic connections are becoming common for network operations. How about for WAN (Wide Area Network) connections? Are you limited to what’s available on Ethernet over Copper or forced to abandon Ethernet for an unrelated telecom protocol?

Not any more. Ethernet connections have become established and far more common than you might think. This does include the lower bandwidth options over twisted pair copper, but it also includes high speed services over fiber optic connections. With fiber, you can pretty much have all the bandwidth you care to pay for. That payment may also be a lot less than you think.

Ethernet over FIber or EoF offers a set of high bandwidth services that meet the specifications of the Metro Ethernet Forum (MEF). All together, these standardized services are referred to as Carrier Ethernet as distinguished from Ethernet that runs on a local area network. These two types of Ethernet are highly compatible. Carrier Ethernet runs in the switched configuration only. There is no CSMA/CD capability. This is actually the way most networks run today. Nearly all use switching and routing to gain full duplex performance. Carrier Ethernet also has provisions for OAM or Operations, Administration and Maintenance that is needed by carriers to ensure that the link keeps working reliably.

There are some real advantages in having standardized services available that meet the MEF requirements. Like standardized equipment, you know what you are getting and that it will interoperate or work with similar services from other vendors. Part of the rapid expansion of Carrier Ethernet is due to the ability of exchanging traffic between service providers through an Ethernet NNI or Network to Network Interface. All carriers have limited fiber optic assets and would be constrained by their own service footprints if they couldn’t interconnect with other carriers. By entering into traffic sharing arrangements, it is possible for carriers to span the nation and the globe.

Two of the standard Ethernet services you may be interested in are E-Line or Ethernet Line and E-LAN or Ethernet LAN service. E-Line is the equivalent of the point to point private line available with T-Carrier and SONET telecom services. E-LAN is something different. This is a multipoint connection that can be used to network multiple business locations as if they were on the same bridged LAN. Everything operates at layer 2 so that switched Ethernet is available across town or to the other side of the globe.

Carrier Ethernet connections are through ports on a UNI or User Network Interface. Typical fiber optic port speeds mirror standard LAN speeds of 100 Mbps Fast Ethernet, 1000 Mbps GigE and 10,000 Mbps 10GigE. This differs a bit from standard telecom services that have unique circuit interfaces for T1, DS3, OC-3, OC-12, OC-48, etc. Many carriers find it easy to install Gigabit Ethernet ports as a standard practice and then rate limit the bandwidth to the amount ordered by the customer.

The port itself will accept traffic at any speed up to the limit of the port capability. Let’s say that’s 1 Gbps. Since you have only ordered and are paying for 150 Mbps bandwidth, that’s what you’ll have on your Ethernet Line or LAN service. The real beauty of this system becomes apparent when you need to upgrade from 150 to 500 Mbps. All you need to do is call your service provider and notify them of the change. They’ll adjust the rate limit to increase your bandwidth up to the 500 Mbps level. There is no physical change to any of the equipment in the signal path. That means the change can be implemented in a matter of days or hours rather than weeks or months.

Ethernet bandwidth services often have many bandwidth increments available. You don’t have to jump from 150 to 500 Mbps. You may be able to get 200, 250, 300, 400 or some other increment offered by the carrier. Most carriers have a fine layer of granularity available because it’s all done in software.

Can you make good use of fiber optic Ethernet connections to the Internet or other business locations? If so, get prices, features and bandwidth levels available for optical Ethernet connections to your business location.

Getting Network Connections Into Europe

While many companies need only domestic WAN connections to run their businesses, an increasing number need links to other parts of the world. European markets are especially important for financial trading and sales & support within the EU. The question is how domestic US organizations get connected into Europe and how they do that cost effectively.

The good news is that there are a number of carriers that span the Atlantic and offer connectivity into major European cities. Some American-based carriers have arrangements to hand off traffic to data centers in Europe. AboveNet recently announced just such an arrangement with ancotel GmbH of Frankfurt, Germany.

Hooking up with ancotel’s Kleyer 90 data center gives AboveNet access to more than 430 service providers who represent 63 countries. These include bandwidth services, VoIP providers, hosting companies, content delivery networks and cloud networking. About 75% of the traffic that goes in and out of the Frankfurt data center is routed to destinations outside of Germany.

In addition, Frankfurt itself is a major financial hub for Europe. AboveNet specializes in low latency connections that support high speed trading. They offer a Gigabit Ethernet service between New York and London with the extreme low-latency needed for algorithmic trading and the secure completion of financial and banking transactions. AboveNet’s low-latency transatlantic service reaches the key financial locations in London including, Slough, The City and Docklands. In the New York Metro area, they connect you with Manhattan and New Jersey, including Newark, Weehawken, Secaucus, Carteret and Clifton. Metro access under 1 msec to hundreds of buildings in the New York and London metro markets.

Another carrier with a global reach is Level 3 Communications. They have multiple fiber optic connections from the New York metropolitan area cross the Atlantic and landing in England, France, Ireland, Denmark and the Netherlands. From there, fiber networks connect to Germany, Spain, Italy, Norway, Sweden, Finland and other European destinations. They have an extensive network covering North America, so that your traffic is on-net even if you aren’t located on the East Coast.

Global Telecom and Technology also has extensive network connectivity in the United States and Europe. They have access to over 100,000 point of presence (POPs) worldwide and experience with installing networks in over 80 countries. GTT offers both international WAN connectivity and International Dedicated Internet Access (DIA).

What kind of international connectivity can you expect to find? The classic solution is a point to point telecom connection running over fiber optic undersea cable. At the low end are T1 lines in the United States and E1 lines in Europe. These run at 1.5 Mbps and 2 Mbps respectively. Faster services are the SONET/SDH fiber optic connections from OC-3 at 155 Mbps on up to OC-192 at 10 Gbps and perhaps OC-768 at 40 Gbps. Network cores are currently being upgraded to 100 Gbps. An alternative service is Carrier Ethernet at 10 Mbps on up to 10 Gbps. Ethernet can be configured as a point to point dedicated line or a point to multipoint connection to link multiple locations.

MPLS networks are becoming increasingly popular for international network connections. You can interconnect all your domestic business locations with a mesh network connection running over MPLS. That MPLS network can also include locations in Europe or elsewhere across the globe. What MPLS offers is high performance, security and lower costs than multiple point to point line connections.

Does your business need access to Europe to include sales, distribution or manufacturing? Do you perhaps have special requirements such as high bandwidth or ultra low latency for financial services? If so, there are telecom services available to meet your needs. In many cases, you can get multiple competitive bids for international network connections and choose which carrier to do business with.

Mix and Match Interconnection Services With Telx

In the cloud, it’s all about connectivity. In fact, connectivity is becoming the weak link in the chain as cloud service providers establish larger, faster, more robust clouds. You may be able to compute at Terabits per second, but that doesn’t help if you can’t get the data in and the results out fast enough. Inadequate connections threaten to stifle innovation in the cloud. That threat is being met by a new suite of service options from Telx called the Connect Portfolio.

Telx made its name in colocation. Their 17 data centers nationwide offer world-class facilities for space & power, HVAC protection, redundancy, security & access controls. If Telx had remained a colocation center, they would be among the top choices for outsourcing data center facilities. But what Telx saw, that others are only now starting to realize, is how the cloud would so quickly become the service model of choice.

The other core competency that Telx has developed is connectivity. They were into connectivity before most companies realized how critical it would become in cloud-centric world. The original impetus for Telx’s connectivity portfolio was in support of their colocation customers. Moving your servers to a colo facility gets you off the hook for providing your own backup power, environmental control and security. You still need to worry about how you will connect to the world. That’s where having an extensive suite of connectivity options gives colocation a leg up on private data centers. The bigger the colo, the more carriers want access to the meet-me room. How many carriers are going to establish POPs in your company’s communications closet?

In a sense, Telx has captured the cloud. Instead of being satisfied with being a high bandwidth switchboard that connects many companies to many bandwidth providers, Telx has invited cloud service providers to move in to Telx facilities. With a suite of cloud providers in-house, businesses needing high performance cloud access are invited to do the logical thing and move right on into Telx facilities also. It doesn’t take long before there is a big cloud of providers and a large field of users that interconnect without ever leaving the building.

What’s the advantage of that? The big one is minimal latency along with nearly unlimited bandwidth. Connectivity is short runs of copper and fiber cabling run through a central patch panel. Latencies are measured in nanoseconds and microseconds. All the switch, router, regenerator claptrap associated with long haul networks is eliminated.

Another advantage is cost. Within a Telx facility there are multiple service providers for everything vying for your business. That’s a lot different from trying to convince a carrier to build out a fiber run to your facility and have them eat the cost. With the effort of in-house connections being almost trivial, construction costs disappear from the decision process. It’s then a buyer’s market for companies who’s equipment racks are surrounded by service providers.

So important is the cloud, that Telx has rebranded its colo facilities as C3 Cloud Connection Centers. Within those centers, customers can choose from a suite of connectivity options in the Telx Connect Portfolio. These are divided into four categories. Dynamic Connect includes EtherConnect, Video Conferencing Connect and Carrier Connect. The Direct Connect option offers ultra low latency connectivity through use of passive Cross Connect interconnection panels. The IP Connect option focuses on IP networks within the Telx C3 data centers, accessed through the Telx Internet Exchange and Dedicated Internet Access products. The Network Connect option lets businesses establish multiple location connectivity, including a Metro Connect option that connects multiple data centers within the same geographical area.

Are you frustrated with the limited connectivity options available to your company? You may be a candidate for high performance interconnection services from Telx and other high performance service providers.

New Low Latency Fiber Optic Services For Atlanta

Atlanta, Georgia is a major hub for fiber optic traffic serving the United States and International destinations. It’s also the home of many Fortune 500 companies and thousands of enterprises in need of high performance bandwidth services. AboveNet has recognized a growing need in the Atlanta metro market and is making a major expansion of its low latency fiber optic routes for downtown Atlanta, Alpharetta, Buckhead and Norcross.

AboveNet is a highly competitive carrier that focuses on high bandwidth connectivity. They operate about 2.3 million fiber miles in top US and European markets feeding more than 2,800 optically-enabled commercial buildings. Their major hubs in the SouthEast are Atlanta and Miami, with others in Houston, Austin, Dallas, Phoenix, Los Angeles, San Francisco / San Jose, Portland, Seattle, Denver, Chicago, Boston Philadelphia, Baltimore, The New York Metro Area and the Washington DC Corridor. In addition, AboveNet connects to Asia in Tokyo, Japan and to Europe in London, Amsterdam, Frankfurt and Paris.

These AboveNet hubs are connected by DWDM (Dense Wavelength Division Multiplexing) equipment that terminates the fiber runs. Most backbone trunks offer 10 Gbps, with individual city locations providing up to 40 Gbps connectivity for carriers and companies that need this capacity.

AboveNet is making its complete suite of high performance bandwidth services available to businesses in the Atlanta metropolitan area. These include both Metro Area Network (MAN) and Wide Area Network (WAN), plus WDM Wavelength Services, Metro Ethernet, WAN Ethernet and IP Transit.

Few providers can offer wavelength services for MAN users. These include standardized Carrier Ethernet services that have the MEF 9 and MEF 14 certificates. Single wavelength service offers a 40 Gbps, 10 Gbps, 2.5 Gbps or 1 Gbps wave service to extend your corporate LAN/WAN to multiple metro area locations. Data mirroring can be done with a Fiber Channel, ESCON or FICON wave. Both protected and unprotected options are available.

Metro WDM applications include virtualization and the serverless office, real time transactions backup and high speed business continuity, streaming multimedia, Storage Area Network (SAN), delivering mission critical enterprise data and applications, and e-commerce transactions. There are basic, enhanced and custom wave solutions to meet any business requirement up to 40 Gbps.

WAN services allow you to reach beyond your metro area to connect with other metro locations are around the world. eXpressWave long haul optical transport is a point to point inter-city connection service that supports voice, data and video between more than 78 city pair combinations. Bandwidth options include 1 Gbps, 2.5 Gbps and 10 Gbps going from POP to POP. Metro connectivity is available in top US and European cities for companies with national and international business locations.

Do you have a business in the Atlanta metro area or other major city in the US that needs very high performance connectivity for metropolitan, national or international business needs? If so, get pricing and features for the fiber optic bandwidth solutions you need from AboveNet and other high performance carriers.

What is an Ethernet Connection?

When we think of connecting to the outside world, what comes to mind is traditional telecom services. Those include POTS and PRI telephone lines for voice and T1, DS3 and OCx SONET for data. A newer technology that deserves a closer look is Carrier Ethernet. It’s Ethernet in the WAN to match up with Ethernet on the LAN.

The idea of extending an Ethernet connection from your building or campus to the Internet or another facility on the other side of the country might seem a bit odd at first. After all, the legacy telecom carriers have pretty much owned that space for over a century. That’s all changing fast. New competitive service providers are coming into the bandwidth marketplace without the history or traditions of using telco standards to define their networks. That frees them to take a “blank sheet” look at what a Wide Area Network (WAN) should be, how it should be priced and what services it should offer.

Let’s say, for the sake of discussion, that the WAN starts where the LAN leaves off. I know that there’s often something called the MAN or Metropolitan Area Network in-between. MAN and WAN technologies are more alike than different. It’s mostly a matter of scale. While the MAN tends to cover a city and perhaps suburbs, the WAN has no geographical limitation. WAN services can be regional, national or even international.

Now let’s consider Ethernet WAN connections. Ethernet is the packet switching protocol now nearly ubiquitous on Local Area Networks. It wasn’t always that way. Even a few decades ago, there were competing standards such as Token Ring. Ethernet has become so popular now that the economy of manufacturing scale makes it more economical to implement than other standards. Ethernet has taken over the LAN, but it is just starting to make inroads on the WAN. In the coming decades, we may see a repeat of Ethernet dominance for local, metropolitan and wide area networks.

The Metro Ethernet Forum (MEF) has done the standardization work necessary to establish what’s known as Carrier Ethernet. This frees LAN Ethernet from its distance limitations so that it can connect from your building to the other side of the world. The MEF has also standardized Ethernet services so that the Ethernet you get from one carrier is the same as you get from another. This makes competitive bidding possible, driving down the cost for the buyer. It also enables carriers to extend their service footprint by interconnecting with other carriers through Ethernet Network to Network Interfaces (E-NNI).

WAN Ethernet has some definite advantages over the legacy telecom services we’re used to. First is the interface. If you want to connect to a T1 line or DS3 service, you need a specialized piece of equipment or a very specific plug-in module for your router. You can’t just take an Ethernet patch cord and connect your edge router to the carrier’s “smart jack.” The protocols are completely different. However, you can do exactly that with an Ethernet connection. Most often the carrier provides a common RJ-45 jack or a managed router that you simply patch into.

Second is services. You can order Ethernet Line Service to mimic the point to point or last mile dedicated Internet connections that you have with T1 or DS3. You can also order Ethernet LAN service. That’s a multipoint networking service that ties together multiple business locations. You don’t need to mess around with running individual private lines to each location. They all connect through the Ethernet LAN service.

Unlike T-Carrier and SONET services, Ethernet is highly scalable. In other words, you can get a wide range of bandwidths delivered to your installed Ethernet port. That will prove valuable if business suddenly increases and you need to increase your WAN bandwidth to handle the traffic. A change in bandwidth level can often be handled with a telephone call to your provider, with no need wait for equipment to be replaced.

Finally, Ethernet WAN connections have a cost advantage. It’s not uncommon to get twice the bandwidth for the same price as a T1 line. At higher speeds, the cost savings is even more dramatic.

You owe it yourself to at least compare services and pricing for Ethernet WAN connections to what you have now to see if you may be missing out on cost and performance benefits. Ethernet WAN is available over both twisted pair copper and fiber optic cabling.

150 Mbps Ethernet vs OC3 Cost

When DS3 bandwidth at 45 Mbps isn’t enough anymore, it’s time to take a look at higher service levels. So, do you make the jump to OC3 at 155 Mbps or take a look at competing Ethernet services? It can be worth your while to do the comparison. Let’s see why.

Once you start moving into higher bandwidth services, you are looking at fiber optic delivery. Yes, in rare situations you may qualify for 100 Mbps or higher Ethernet over Copper or fixed wireless microwave service. For these to work you need to be very, very close to the provider’s office and, in the case of microwave, have a clear line of site from your building to theirs. For everyone else, it’s fiber optic cabling. Fiber can transport Ethernet or OC3 equally well. So, how do you choose?

One big factor in your decision may be the cost of construction. If there is fiber running nearby, but not yet installed into your building, there is a certain one time cost involved in trenching the fiber and its conduit underground or bringing in the fiber cable overhead. Oddly enough, in densely packed downtown business districts, the cost of fiber construction can be higher than it is out in the burbs. Why? It’s because the available conduits may be all full or hard to obtain and the expense of tunneling under major roadways can be a deal breaker.

Don’t be discouraged by the possibility of high construction costs until you get competitive quotes for fiber optic service to your building. Each situation is unique. The cost for installing similar service to buildings across the street from each other can vary wildly. It’s also possible that you may get your installation for free or at a big discount. Some fiber providers are aggressively building out their networks. If they want your location, they may foot the bill for construction or at least part of it. The more bandwidth you need, the more attractive your situation is. If you are in a multi-tenant building, it could be worth your while to get together with other tenants and offer a much larger bandwidth requirement to lure potential service providers.

Another possibility is that your building is already “lit” for fiber optic service from one or more carriers. Let’s say that someone in your building is already leasing OC3 bandwidth from a telecom carrier. That carrier has already gone to the expense and trouble of bringing in the multi-strand fiber cable and installing termination equipment. They’ve hooked up the other end to their metro fiber network running nearby. How much trouble is it to also provide you with OC3 fiber optic service?

Not much trouble at all. Unlike copper cables, fiber optic bundles can support nearly unlimited bandwidth. It’s a matter of setting their add/drop multiplexers to bring enough bandwidth into the building and demultiplex it into separate services for each subscribing tenant. As you can imagine, the construction costs will be minimal, perhaps even complementary.

The same is true if there is already high bandwidth Ethernet over Fiber service installed in the building. The Ethernet service provider has done all the hard work. They can easily add you to the network rapidly and at minimal cost.

This may be the deciding factor. If one service is already installed and the other is not, the capital cost factor can outweigh other advantages. What if both services are in the building? Then it becomes a more level playing field. In general, Ethernet service is less expensive and easier to scale than SONET services, such as OC3. There is also a service called Ethernet over SONET that uses traditional SONET ring networks to carry the newer Carrier Ethernet protocol. That means a legacy carrier may well be able to offer you either OC3 or 150 Mbps Ethernet at an attractive price over already installed infrastructure.

How much will it cost you to get the high bandwidth business connectivity you require? Each situation needs to be evaluated on its own merit. You can get cost quotes for Ethernet services up to 1 Gbps instantly, with fast response on SONET or Ethernet over SONET services by using the Fiber Network Quotes service for US based locations. US to international destination quotes are also available upon request.

Telecom Providers Build Their Own Clouds

Just as cloud companies are beginning to mature as businesses, Internet service providers and other carriers have decided to build out their own cloud offerings. Now, how does a harried IT manager or small business owner sort through all the various opportunities?

It’s important to remember that we are in the early days of the cloud. Like all new technologies, this one has a maturity or learning curve. We are on the early part of the upward slope. What that means is a lot of activity from a lot of players. You can expect new companies with new services to be popping up all the time. It also makes sense that current players in the computer and networking space will want to corral as much of this business for themselves as possible. If not, they may be justifiably concerned that they could be relegated to sidelines.

Windstream, a major competitive carrier for T1 lines, MPLS networks, dedicated Ethernet Internet and enterprise VoIP, saw the handwriting on the wall when they acquired Hosted Solutions last year. Adding the assets of Hosted Solutions to Windstream’s existing data centers, has given them the critical mass to get into cloud services for existing customers. Such services include such things as cloud storage, Infrastructure as a Service and private, public, and hybrid clouds. Other carriers, such as Level 3 Communications, also have cloud services available.

Most carriers have large data centers for their own use. They often leverage these assets by offering colocation services within their secure and highly reliable facilities. Colocation is something of a forerunner of the cloud. The provider offers racks and cages where you can move your servers and network appliances. They provide the electricity with backup, environmental control and security. Another big draw of colocation is the proximity to large amounts of bandwidth. Many companies either can’t get or can’t afford the cost of constructing fiber optic connections to their own facilities. At a colocation center, the carrier is right down the hall and a mere cross-connect away. It’s the best deal on bandwidth you can get.

More recently, colocation centers have begun to offer contracted technical support and even leased servers for those who don’t want to buy their own. In essence, the colo becomes your data center and you don’t need the capital expense, operational expense or staffing to run your own. That being the case, what’s different about cloud services?

The primary difference between colocation and the cloud likes in both outsourcing and virtualization. The cloud infrastructure consists of massive computing power and storage, all virtualized so that it can be sliced and diced as users require. While in the cloud, you are unaware that you are not the only one using the facilities. The same bank of servers that run your applications can be running dozens or hundreds of others simultaneously. The magic of virtualization creates the illusion that you have one or more physical servers all to yourself.

A good cloud is much more than that. Not only do you rent rather than buy, but you rent by the minute or hour times the number of servers you are using. You can add or subtract virtual servers at will and only pay for the ones you are reserving. The same is true for storage. You don’t worry about buying a new disk when you fill up the one you have. You simply increase or decrease storage as needed and pay by the byte.

The ability to increase and decrease resources almost instantly is a feature unique to the cloud. This scalability is highly desirable for companies with varying loads or ones that are rapidly growing. There is no need to be constantly buying and upgrading equipment when you can simply log into your cloud account and add resources at will.

What carriers bring to the table is one stop shopping. They already provide last mile access, multi-site connectivity, and converged voice, video and data networks. By adding cloud services, you have one bill to pay and a single point of contact for resolving issues such as latency or availability. Independent cloud service providers will need to be on their toes to stay ahead of the carriers, by offering more advanced services and lower pricing to stay in the game long term.

Are you ready for the cloud? The range of services and competitive pricing makes cloud computing and storage, colocation and managed services more cost effective than they’ve ever been. Inquire about availability and pricing for the networking and computing services you need for your particular applications.

Cloud Service Providers Colocate With Customers

There’s a new migration on. No, not the migration from local data centers to the cloud. It’s a migration of cloud service providers to colocate with their customers.

Why? It’s the rude awakening that companies suffer when they find that applications running way out there don’t have the same zip as the ones running on servers down the hall. That can be fixed, of course. It requires engineering your connections to the cloud so that they have sufficient amounts of bandwidth and very low latency, jitter and packet loss. But why go that that expense when you can just cozy up to your service provider with little more than a long patch cord connecting you?

That’s what Telx thinks. They’re throwing open their doors and working to lure cloud service providers to take up residence in one or more of their high performance colocation centers. It’s an acknowledgement that the speed of computing has gotten to the point where interconnections are the weak link. The venerable T1 line or DS3 connection that worked so well when all you needed to do was surf the Web, exchange email or generate sales leads quickly chokes when you start adding virtual servers by the dozens or hundreds.

There are a couple of big crunches that strain the cloud service model. One is business processes that are now automated and support hundreds or thousands of employees. The other is high performance e-commerce, with enormous catalogs and thousands of simultaneous shoppers who have little patience for sluggish servers and none at all for errors in their shopping experience.

The cloud is becoming a victim of its own success. Cloud service providers have mastered the technology of being able to ramp up or down the number of servers online in a matter of seconds. Storage is a bottomless well that data fills as needed. Public-facing bandwidth is easily handled with multiple Gigabit and 10 Gigabit Internet connections with enough margin to serve all customers. While cloud companies have gotten used to this scale of resources, most businesses have not. They don’t have the private line connectivity to take full advantage of near-infinite, near-instantaneous computing resources.

More savvy companies have mastered the connectivity issues, but who’s going to turn down the opportunity to get more performance for less money? The notion of being on the same floor of the same building with your service provider and ditching the telecom line in favor of a local fiber or wire connection has a lot of appeal. The issues of bandwidth, latency, jitter, and packet loss simply disappear.

A lot of medium and larger companies already have equipment in colocation centers, such as Telx. The economic tradeoff between running your own environmentally controlled facilities with backup power, fire suppression and round the clock monitoring and simply renting space in a larger facility with its economies of scale makes colocation attractive. On top of that is the fact that you have easier access to competitive carrier services with more attractive pricing than you can get locally. Now, add to these advantages the opportunity to connect to a cloud service provider in-house and you are looking at really attractive cost vs performance figures.

The new Telx Cloud Connectivity Centers with cloud-optimized infrastructure to support cloud service providers in each of their 15 data centers is an idea who’s time has come. Enterprise users and cloud companies are like opposite magnetic poles trying to get as close to each other as possible. Colocation is the obvious answer.

Can your business benefit from colocation as a service provider or service user? Get pricing and technical specs for the IT resources you need and compare with what you are doing now.

Dark Fiber Community Builds Infrastructure

You hear the stories that our infrastructure is crumbling. Not all infrastructure. There’s a big construction project underway now to ring the country with a thousand fiber strands, a high bandwidth nervous system for information technology. Lighting up this dark fiber promises almost unlimited low latency bandwidth for the foreseeable future.

Why the need for this dark fiber infrastructure? It’s not so much that the old infrastructure is crumbling as it is chock full. You remember the great fiber buildout late last century? It seemed to be way overdone when the tech crash came. Indeed, it’s taken over a decade to light up all that excess fiber. There may still be some underutilized fiber rings looking to see the light, the laser light that is. But there is also an enormous additional need coming from business process automation, high frequency financial services, electronic medical records, and 4G wireless, to name a few demanding applications.

Rising to the challenge is Allied Fiber and its Dark Fiber Community. Allied fiber isn’t a carrier. They are an infrastructure builder. They are where the carriers go to get new unlit fiber routes. One of the most prestigious fiber optic carriers, AboveNet, has just joined the Dark Fiber Community to provide expertise in high performance fiber optic networking and be part of this enormous resource.

The Dark Fiber Community is an association of over 60 members that include equipment vendors, carriers, industry technical associations, financing companies and other interested parties. It’s hosted by TMCnet.com as an online resource and educational platform to support Allied Fiber.

Allied Fiber, itself, is the company that is building out and leasing this enormous national dark fiber optic backbone. It will eventually be in the form of a ring linking New York City, Chicago, Seattle, Los Angeles, Phoenix, Dallas, Houston, Jacksonville, Miami, Ashburn, VA and back to NYC. Draw a circle around the lower 48 states and you’ll have the general route for Allied Fiber.

But what if you don’t happen to be located in one of those major cities on the fiber route? Here’s the cleverness of the design. It’s not just a few long haul fiber routes. It’s two parallel routes. One is long haul between the major cities mentioned. The other, running side by side, is broken up into 60 mile segments. These short haul routes terminate in colocation huts where the laser signals are regenerated to boost them for the next segment. Inside the same hut are racks for multiplexing equipment to add and drop network services on the route. This long-haul/short haul arrangement allows Allied to provide low latency fiber between major city pairs while having the flexibility to also serve many other locations along the way and connect to other short haul routes off the major route.

One series of connections will be Fiber to the Tower or FTTT. You may not have heard of FTTT before, but you will hear plenty about it in the near future. The wireless industry is moving into 4G as fast as they can. Unfortunately, their old T1 based copper backhaul infrastructure is maxed out for bandwidth. That means new fiber connections to those cellular base stations in many cases. Allied’s FTTT plan is to provide access to the duct fiber every 1 to 2 miles in order to create lateral extensions from the main fiber route to where the towers are located.

Are you in need of higher bandwidth fiber optic services at highly competitive prices? If so, you may have more options than you think. Find out by getting prices and availability for dark and lit fiber optic bandwidth services now.

What is Metro E?

Metro E is short for Metro Ethernet, a popular and rapidly expanding network connection service.

Metro E is Ethernet like the protocol you run on your Local Area Network (LAN). But it has been standardized and adapted to also run on a Metropolitan Area Network (MAN). The organization behind this standardization is the MEF or Metro Ethernet Forum. It’s an industry standards organization dedicated to Carrier Ethernet.

Here’s why you should you know about Metro E and seriously consider using it for your business connectivity. Metro Ethernet services are better suited to today’s packet switched networks than the legacy telecom services such as T1. Connectivity is almost trivial. Ethernet is what nearly all networks are running as a protocol. The connection from your service provider is an Ethernet jack. That’s it. No need for special conversion equipment to connect to your switches and routers.

Metro E is supported by a number of incumbent telecom carriers, plus many new competitive service providers that have no connection to legacy telephone services. Nearly all of these new competitors have built their networks on fiber optic lines and IP or MPLS core networks. Metro Ethernet services are easily transported on these networks. The result of all this competition is that Metro E prices are often considerably lower per Mbps than T1, DS3, or OCx bandwidth. It is not uncommon to get 3 Mbps Ethernet service for the same price as 1.5 Mbps T1 and similarly reduced costs at higher bandwidths.

Like other telecom services, Metro Ethernet can be set up to provide point to point connectivity between two business locations. Unlike older technologies, Ethernet Line Service can be configured as a layer 2 connection between two LANs, effectively connecting them to make one larger LAN. Ethernet LAN Service, or ELAN, can do the same thing for multiple locations. It’s a high performance and cost effective way for businesses to tie-together branch offices, factories, headquarters and warehouses. It works just as well for hospitals and their related medical centers in the area.

Another use for Metro E is as an access network connection. Metro E links are used as last mile connections to larger MPLS networks for national or worldwide service. They are also used as dedicated broadband Internet connections for small, medium and large organizations.

Metro E bandwidth tends to be easily scalable. Service at 3 Mbps is a popular entry level bandwidth. Many companies move up to 10 Mbps, a standard LAN speed. Fast Ethernet at 100 Mbps, 1000 Mbps and 10 Gigabit Ethernet are other standard LAN speeds that are also supported by Metro E providers. While these speeds are popular, most providers offer incremental bandwidths between each of these levels. You can order any bandwidth up to the limit of your installed Ethernet port. Start with what you need now and easily upgrade as the need arises.

One thing you should know is that the Metro in Metro E generally means just that. This service is available in most metropolitan areas, but rarely in rural areas. It may be possible to get Ethernet connectivity over T1 lines, called EoDS1. This is a way to extend service to include remote business locations.

If Metro E the right service for your business situation? A quick way to find out is to request a list of Metro E service levels and prices for your business location or locations.

Ethernet MPLS Has Cost and Bandwidth Advantages

Two of the hottest voice, video and data networking technologies right now are Carrier Ethernet, also known as Metro Ethernet, and MPLS networks. But did you know that Ethernet and MPLS can work together to give you more bandwidth at lower cost?

What Ethernet brings to the table is a way to avoid the big protocol speed bump that has traditionally existed at the demarcation point between customer network and telecom network. These two networks have very different historical development and would be completely incompatible were it not for some very clever interfacing. Today it is possible to transport packets from one LAN to another LAN via a telephony-based telecom network designed for voice channels, not datagrams. But why should you?

With Ethernet in the metropolitan and wide area networks, the speed bump between inside and outside networks disappears. Ethernet packets flow seamlessly down the line as far and the connections exist. Often that is right into a branch office or other remote site LAN owned by the same company. Metro Ethernet point to point line service makes it easy to interconnect business locations.

Because it is Ethernet all the way, there is an extra advantage to Ethernet transport services. These connections can be set up to operate at the layer 2 switching level rather than layer 3 routing. That gives you the ability to connect your headquarters LAN to a branch office LAN or remote data center and create what amounts to a very large bridged network for your entire company.

So where to MPLS networks fit into this? MPLS or Multi-Protocol Label Switching is a technology that accommodates just about any protocol. You can use it to transport telephone calls, data backups, video feeds, and anything else you need to get from point A to point B. In a way, an MPLS network is something like a postal or shipping service. It doesn’t care what’s in the boxes. It just gets them there on time and undamaged.

MPLS networks are an alternative to the public telephone network or the Internet. They are operated by telecom carriers with regional, national or international service footprints. What MPLS networks offer technically are carefully engineered network services with guaranteed bandwidth, jitter, latency and packet loss characteristics. What they offer economically are very cost effective ways to transport your sensitive voice, video and data with a high level of quality and security.

Now, combine Ethernet and MPLS and what do you get? You get the performance and cost advantages of Ethernet connections from your business locations to the MPLS network cloud. Within the network, your Ethernet packets are transported transparently between locations. You simply specify what type of connectivity you want among the locations you choose and the service provider sets that up.

Ethernet MPLS solutions are readily available and highly competitive. That provides an opportunity for you to consolidate your telecom services and reduce costs while maintaining quality of service. Check Ethernet MPLS pricing and availability now.

MiFi Points The Way to Wireless Transition

Verizon Wireless just made an amazing announcement. They will be selling the Apple iPad in their stores. But aren’t Apple and AT&T exclusive partners? Indeed. So, why is Verizon selling a product that won’t work on their network? ...Or will it?

Yes, it will. How Verizon accomplished this clever feat of engineering points the way to the future of wireless broadband. Actually, not the future future. Just the immediate future. Call it the era of wireless transition.

Wireless technology has pretty much developed along two lines. One is the telecom carriers, including AT&T, Verizon, Sprint and T-Mobile. There are other players in the cellular wireless game, but they are simply private branded versions of the big four within the US. What characterizes the major carriers is that their offerings are proprietary. What works on AT&T won’t work on Verizon Wireless, and vice versa.

The other wireless path is an industry standard known a WiFi. It comes in flavors such as a, b, g, and n. But unlike telecom carrier services there is enough commonality and backwards compatibility that pretty much any WiFi device will work on pretty much any wireless router, hotspot or access point.

What Verizon has cleverly done is marry the two lines. They can’t get into the iPad through the front door, so the come in the back door. How? Very simple. They use an interface device to convert cellular to WiFi. That device is the MiFi. The Verizon MiFi is a little box about the size of a pack of cards. Inside is a cellular radio, a WiFi radio, a battery and some circuitry to make it all work. All you do is push a button to turn it on and the converter works automatically. It allows up to 5 wireless devices to gain access to the Verizon 3G wireless network as if they were Verizon-enabled to begin with.

The Verizon iPad will consist of an Apple iPad and a Verizon MiFi bundled together. They are separate pieces of equipment, but the MiFi will slip into your pocket or bag so it isn’t intrusive. At first blush, it may seem like having to carry around two pieces of equipment instead of just one is a big disadvantage for Verizon compared to AT&T. But Verizon may get the last laugh after all. The MiFi provides 3G connectivity for your iPad, but it also provides 3G connectivity for your other devices that don’t have their own 3G service built-in. That includes your laptop computer, netbook, games, and even your Apple iPod. If you had to buy separate 3G service for each device, you’d go broke. But one MiFi can serve whatever gadgets need connectivity, as long as they are WiFi enabled.

Verizon isn’t the only one with a MiFi. Novatel, maker of the MiFi, offers an unlocked version for GSM carriers AT&T and T-Mobile. There’s a MiFi specifically for Virgin Mobile. Sprint goes one further with their Sierra Wireless Overdrive 3G/4G Mobile Hotspot. It works on both the Sprint 3G Mobile Broadband network and its 4G WiMAX network. CLEAR offers a similar 3G/4G converter called Clear Spot.

Even these converters are transitional technology. Smartphones, starting with the Droid X by Motorola and Samsung Epic, have the cellular to WiFi hotspot capability built-in. This is likely to become a standard feature on smartphone designs, as WiFi and Bluetooth are the industry standard wireless technologies. WiFi has the greater transmission range.

Down the road a few years, the tide of wireless seems to be going in the direction of standardizing on LTE as a 4G standard. Cellular phone may give way to VoIP over LTE. At that point it will be hard to tell the difference between a mobile phone, a smartphone and a digital device like a tablet computer. Perhaps a single smart radio chip will provide universal wireless connectivity. Just pick your carrier and sign up for a service plan after you buy the device. The wireless transition era will be complete.

Fiber Optic DWDM Up to 100 Gbps Per Wavelength

The incredible growth of bandwidth demand continues unabated. Odd, perhaps, in these soft economic times. It’s the proliferation of video and especially high definition video that has dramatically increased network bandwidth requirements, including metro and long haul WAN networks. Now a new benchmark has been achieved at 100 Gbps per wavelength in DWDM or Dense Wavelength Division Multiplexing fiber optic systems.

It wasn’t all that long ago that we were hearing of the move from 10 Gbps to 40 Gbps channels. Alcatel-Lucent is offering a new upgrade module that operates at both 40 Gbps and 100 Gbps using a single optical carrier. It’s available in their 1830 Photonic Service Switch (PSS).

What does it take to achieve such speeds on existing fiber that was intended for 10 Gbps transmissions? After all, you can’t exactly rip up all that installed fiber and lay new cables just to up the bandwidth. Also complicating the design is that in wavelength division multiplexing not all wavelengths will be scheduled for simultaneous upgrade. What’s needed in an upgrade that won’t interfere with existing 10 Gbps and 40 Gbps signals nor demand larger amounts of rack space and power.

Alcatel-Lucent has met these design goals with a new electro-optics engine that depends heavily on digital signal processing and better modulation and detection techniques for the optical signal. It starts with a change from amplitude shift keying (ASK) to phase shift keying (PSK). With a constant amplitude, the signal has better resilience against non-linear effects in the fiber. Both two-phase-state and four-phase-state coding schemes can be used to load more information on the signal. They then double the bit rate again without increasing the symbol rate by adding PDM or polarization division multiplexing on the same signal.

As you probably guessed, transmitting more information on the same wavelength has a price. That price is sophistication of the electronics. Coherent detection uses a local oscillator mixed with the optical signal to produce interferences that give an output of phase, amplitude and polarization to the digital signal processor. Some heavy duty number crunching allows the DSP to compensate for linear distortions in the fiber while it recovers the bit information.

Alcatel-Lucent proved all this out last fall during a field trial in Spain, by transmitting 112 Gbps per channel along with 40 Gbps and 10 Gbps channels on a 1088 km link between Madrid and Merida via Seville, as described in their technology white paper, “Next-generation Electro-Optics Technology with Coherent Detection”.

Ciena has a competing system, the OME or Optical Multiservice Edge 6500 that also runs at 100 Gbps. These two companies should set the standard at 100 Gbps... at least for awhile. You know that whenever there is competition, there will be the competitive spirit to take things to the next level. What is that? 200 Gbps? 500 Gbps? 1 Tbps?

Service providers worldwide are in a scramble to provide higher speed services at lower costs. Prices have dropped so much in the last few years that you can probably afford more bandwidth than you think. Why wonder when you can get high bandwidth fiber optic service quotes quickly and easily. It only takes a minute to inquire, so why not take that minute right now?

TW Telecom's Extensive Service Portfolio

tw telecom is the type of communications provider that's meant by the term "full service." They own and operate a nationwide fiber optic network serving 75 metropolitan markets and over 8,800 commercial buildings. Their network spans more than 26,000 route miles and features a 10 Gbps IP backbone. Need a good price on a T1 line? They've got it. Need long haul Carrier Ethernet service from 2 Mbps to 10 Gbps? They've got that too. Plus just about everything in-between.

If the name tw telecom has a familiar ring, it may come from the company's legacy. The initials "tw" started out meaning Time Warner. That's right. tw telecom (yes, the company name is all lower case letters) started out in 1993 as a joint venture with Time Warner Cable. Later they split from the cable operation and became Time Warner Telecom, LLC. Just this July, they became tw telecom as a publicly traded company. Xspedius, another familiar telecom name in the corporate world, became part of what's now tw telecom in 2006.

tw telecom is the kind of provider you can't outgrow. You may start out with a single T1 data line to get your small business connected. By the time you're a major corporation, you'll have stepped up to dedicated services such as DS3, OC3, wavelength services, private transport SONET rings, and Carrier Ethernet.

Perhaps the newest and most innovative service in business telecommunications is Carrier Ethernet. Often called Metro Ethernet, this is Ethernet that connects multiple locations as if they were on a single company network. tw telecom calls their service Native LAN. With it, you plug into the familiar IEEE Standard 10 Mbps, 100 Mbps and 1000 Mbps Ethernet interfaces. It offers the advantage of a familiar technology and often a lower cost per Mbps than legacy transport solutions.

tw telecom offers both voice and data connections, plus an integrated solution that combines local and long distance telephone plus Internet service onto a single dedicated clear channel T-1 line. This service, called VersiPak, dynamically allocates bandwidth so that when voice channels are not being used, that bandwidth is automatically assigned to the Internet service. This is as popular service for smaller and medium size businesses.

tw telecom is part of the suite of carrier services available for instant online quotations through GeoQuote (tm) from Telarus. You can quickly determine the cost savings for your company with a simple entry into the GeoQuote (tm) voice and data pricing form that you'll find at T1 Rex.
